caclNullCellHeader

Module: CISCO-ATM-CELL-LAYER-MIB

OID (symbolic): CISCO-ATM-CELL-LAYER-MIB::caclNullCellHeader

OID (numeric): 1.3.6.1.4.1.9.9.133.1.1.1.1.1

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: The first four bytes of the ATM header to be used for Null cells. Generally, idle cells are inserted into a cell stream as a mechanism for rate adaptation between the ATM data link layer and the physical layer. The header fields: Generic flow control,Payload type and Cell Loss Priority can be specified in the value of this object. It applies to both transmitted as well as received cells.

What is caclNullCellHeader?

Configures the 4-byte ATM cell header value used for null (idle) cells inserted to adapt the data rate between the ATM data-link and physical layers.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.133.1.1.1.1.1
snmpwalk -v2c -c public <target> CISCO-ATM-CELL-LAYER-MIB::caclNullCellHeader

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.133.1.1.1.1.1.1
snmpget -v2c -c public <target> CISCO-ATM-CELL-LAYER-MIB::caclNullCellHeader.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.133.1.1.1.1.1.1 s <value>
